BellSense: Intelligent Coach

Most apps count reps. BellSense coaches them. Now the coach watches your sets through the camera, speaks while you train, and answers when you ask. Free to start.

BellSense is a kettlebell coach. The app gives you the program, you log the work, and the next session adapts to what you actually did.

Make every rep matter.

How the coaching works, with just your phone Pick a program. Each session tells you what to do. You log your sets and rate how they felt, and BellSense reads everything you give it: reps, effort ratings, volume, heart rate if you wear a monitor, and sleep, HRV, and resting heart rate through Apple Health, combined into a daily readiness score. Then it makes the call a coach would make: add, hold, or back off — decided by your results and recovery, not a calendar.

The logbook decides what you do next.

You can also just ask the coach what to train. It reads your recent sessions and recovery, recommends one session, and tells you why — or ignore it and train what you want.

All of that is free and stays free.

Training programs Programs that run from weeks to months, beginner foundations to advanced power and density work, each with warm-ups, cool-downs, and accessory work. All twenty-six are free.

Supported exercises Kettlebell ballistic: swing, snatch, clean Kettlebell grind: goblet squat, one-arm row, overhead press Kettlebell stability: Turkish get-up, windmill Barbell: back squat, bench press, deadlift, press, row

Barbell lifts are logged and scored alongside the kettlebell work; the structured programs are kettlebell.

Workout modes • Individual: one exercise, tracked round by round • Alternating: two or three exercises paired and rotated each round • Complex: several exercises chained back to back, tracked as one session

Live camera coaching Prop your phone up and the camera counts your training as you do it — squats, presses, rows, swings, and snatches, free. The Swing Trainer reads every swing live with a verdict on each rep. With BellSense+ Live, the coach also speaks while you work.

After every session • The coach's read on how the session went, tied to your own data • The progression call for next time • Volume and trend charts that build week over week

The bell sensor BellSense started as a small sensor that mounts on the kettlebell. It is in development, not for sale yet, and the app never requires it.

BellSense+ An optional subscription. Your coach reads each session and tells you what the numbers mean, with weekly and monthly reviews and an on-demand read of your last 30 sessions. It rebuilds today's session when your readiness calls for it, from 30 sessions of history instead of 10. Tell it you have different bells, something hurts, or less time, and it adapts the day around that. It sets a weekly conditioning target from the training load you actually carried, and it analyses as many lifting videos as you care to send it. Programs, progression, and cardio stay free.
